Abstract

A system adapted to modify refractivity of a cornea of an eye(10), including a first component (22), adapted to be implanted at a first depth in the cornea (14). A second component (26), separate from the first component (22), adapted to be implanted at a second depth in the cornea (14) at a position relative to the first component (22), such that an axis passing through the eye parallel to the optical axis (30) passes through the second component (26) without passing through the first component (22). The second depth is closer to the front surface of the cornea (14) than the first depth.
